Description
The CXD3021R is a digital signal processor LSI for
CD players. This LSI incorporates a digital servo,
digital filter and 1-bit DAC.
Features
All digital signal processing during playback is
performed with a single chip
Highly integrated mounting possible due to a built-
in RAM
Digital Signal Processor (DSP) Block
Playback mode supporting CAV (Constant Angular
Velocity)
Frame jitter free
0.5

continuous playback possible with a
low external clock
Allows relative rotational velocity readout
Wide capture range playback mode
Spindle rotational velocity following method

playback by switching the
built-in VCO
The bit clock, which strobes the EFM signal, is
generated by the digital PLL.
Digital PLL master clock can be set to 2/3 the
conventional one.
EFM data demodulation
Enhanced EFM frame sync signal protection
Refined super strategy-based powerful error
correction
C1: double correction, C2: quadruple correction
Supported during 32
×
playback
Noise reduction during track jumps
Auto zero-cross mute
Subcode demodulation and Sub-Q data error
detection
Digital CLV spindle servo (built-in oversampling filter)
16-bit traverse counter
Asymmetry correction circuit
CPU interface on serial bus
Error correction monitor signal, etc. output from a
new CPU interface
Servo auto sequencer
Fine search performs track jumps with high
accuracy
Digital audio interface outputs
Digital level meter, peak meter
Bilingual compatible
VCO control mode
Digital Out can be generated from the audio serial
inputs.
Supports three types of DA interface
(48 bits/64 bits/32 bits)
DSP, servo and DAC blocks support sleep mode.
Digital Servo (DSSP) Block
Microcomputer software-based flexible servo control
Offset cancel function for servo error signal
Auto gain control function for servo loop
E:F balance, focus bias adjustment function
Surf jump and surf brake functions supporting micro
two-axis
Tracking filter: 6 stages
Focus filter: 5 stages
Servo drive DAC output possible
